Abstract: 317,624. Webster, R. K. July 30, 1928. Heating by electricity. - In apparatus for supplying heated air for hairdressing &c. switches in the circuits of the heater and the motor driving the air blower are so connected with a valve in the air supply pipe that the heater and the motor are put into operation and the air supply valve is opened when the discharge nozzle is lifted from its support. The nozzle 7 is carried on a stirrup 6 which is connected to the arm 5 pivoted on a spindle 2. When the nozzle is lifted from the stirrup, a spring, not shown, causes the spindle 2 to rotate whereby another arm 9 attached to the spindle engages with a sectorshaped portion of the plate 15, 16 which is freely mounted on the spindle 11, and which rotates against the action of the spring 24. In the rotation of the plate 15, 16, the sector-shaped portion engages with a projection 14 on a boss 13 rigidly mounted on the spindle 11, and, in the subsequent rotation of this spindle, the movable contacts 17, 18, 19 of the electric switches are rotated into engagement with the fixed contacts 20, 21, 22 respectively. A cross arm 25 on the spindle 11 is connected by springe 26, 27 to a second cross arm, not shown, mounted on a spindle 29 passing through the pipe 30 and carrying a butterfly valve 31, which is so mounted that the rotatory movement of the spindle 11 causes the valve to open as the electric switches are closed and to close as the switches are opened. When the nozzle is replaced on its stirrup, the arm 9 moves in the opposite direction, engages with the arm 15, and rotates the plate 15, 16 until the arm engages with the projection 14 and reverses the operations described above. The spindle 11 is carried in bearings in bridge members 12 secured to the back 4 of the casing 1; and the fixed contacts 20, 21, 22 of the electric switches are constituted by spring members mounted at their inner ends on insulated bars 23. The switch 17, 20 controls the operation of the electric motor driving the blower which supplies air to the nozzle 7 via a trunk line and the pipe 30, and the switches 18, 21 and 19, 22 are connected in the two leads to the heater which is accommodated either in the nozzle 7 or the pipes 30. A further switch 35 varies the resistance of the heating element or can cut it out of circuit altogether. A further hand-operated valve 36 in the pipe 30 is provided but arranged so that it cannot completely close the pipe. The electric connections to the switches are brought out to insulated terminals 41 on a bracket 42 which is secured to the lower part of the casing 1. When the blower motor is manually controlled. the switch should be linked with a further switch in the heater circuit to prevent the heater operating when the motor is not running. A number of appliances may be connected to the same air supply, magnetic blow-outs for the switches may be provided, and the valve 31 may be made adjustable so as to control the volume of air.
